The GO Regulator C2 Series is a compact dual-stage pressure reducing regulator designed for highly accurate downstream pressure control in analytical, laboratory, semiconductor, and specialty gas applications. The dual-stage design minimizes supply pressure effect (SPE), providing exceptionally stable outlet pressure as cylinder or inlet pressure decreases during operation. This makes the series especially suitable for precision instrumentation and high-purity gas systems where pressure drift must be minimized.

The C2 Series utilizes two diaphragm-operated pressure reduction stages integrated into a compact regulator body, allowing smooth pressure control, excellent sensitivity, fast response, and reliable repeatability under varying operating conditions. Its low internal volume and clean internal design support use with high-purity, corrosive, toxic, and specialty gases. Standard construction materials include 316 stainless steel and brass, with optional Monel and Hastelloy configurations available for aggressive media service. Multiple seat and elastomer material options are available to optimize leakage performance and chemical compatibility.

Available configurations include multiple inlet and outlet pressure ranges, pressure gauge ports, panel mounting options, relief valve configurations, and various threaded process connections. Specialty clean-service and electro-polished configurations are available for semiconductor and ultra-high-purity applications.

Typical applications include gas analyzers, calibration gas systems, chromatography systems, semiconductor process gas supply, laboratory instrumentation, laser gas systems, sample conditioning systems, specialty gas handling, and industrial process installations requiring highly stable dual-stage pressure regulation.
